More Information
Summary:PURPOSE: An asymmetric anthracene derivative is provided to ensure high color purity and excellent luminous efficiency and luminescent brightness and to realize long lifetime compared with a conventional material, and to improve driving voltage, luminous efficiency, color purity and lifetime property. CONSTITUTION: An asymmetric anthracene derivative has a structure represented by chemical formula 1. In chemical formula 1, R^1 - R^3 are independently hydrogen, halogen, C1-30 alkyl group containing or not containing at least one hetero atom among S, N, O, P and Si, C2-40 alkenyl group, C5-60 cycloalkyl group or C5-60 arylalkyl group; and Ar^1-Ar^2 are independently C5-50 aryl group or polycyclic aromatic group, or C5-60 aryl group containing C1-30 alkyl group containing or not containing at least one hetero atom among S, N, O, P and Si, or polycyclic aromatic group.
